This week, NQW visits Stoke Newington. Today's guest is Sam Roberts, Ghostsigns Tour's leader, who talks about his quirky tour focused on spotting the remains of old advertising signs on the walls of the neighbourhood. His two-hour walks tell the stories behind those signs. You can help me in his research (which has gone on for eight years) by contributing to the Ghostsigns Facebook page.
